Re: Main Bearing Clearances / Tolerance

As well as they most likely did not dial in the mandrel before honing as well. I have seen the results of this many times For the good of the order, how do you dial in your line hone mandrel? What is the evidence/result of not dialing in the mandrel? [/quote] If you read through the set up instruct...

Re: lifter valley paint or polish

I just polish. It gets the sand out of the surface and it stops any potential issues from paint coming off a non polished surface. The Glyptal paint does not always stay put for ever. I had an issue after a freshen years ago and the jet wash loosened it causing the oberg to plug and never did it aga...

Re: Questions regarding lg. to sm. journal crank spacers

Working with a 2.3 Ford 4 cyl Pinto engine. These come in either early large main journal or later small journal styles. Roughly a .200" diameter difference between the two. When I can't find a small journal block I use the small journal caps on a lg. block with some .020" under main bearings that ...

Re: LS "out of order"

I am curious if anyone on ST has taken a step back and tested any LS engines utilizing different firing orders and intake configurations? I currently am building a EFI LS with a traditional singleplane 4 bbl configured intake. But with a 4 bbl efi throttle body and injectors positioned about 1.5" u...

Re: block heater

More information, this is a Dart block equipped SBC drag race engine on Methanol fuel. It also has a small radiator and leanout valve for warm-up. My goal is a way to warn the engine without wasted fuel, especially during the cooler season. I am in East Texas so our cooler season is short. During h...

Re: BBC gear drive

does anyone know if the milodon blown / injected gear drive can be used with a flat cover in a normal application ? I'm not blown / injected right now but may be some day. I am sure if can as long as the balancer clears and the timing pointer is located correctly and the WP pulley center line and t...

Re: Main Bearing Clearances / Tolerance

OK Fellas. I'm finally back with some measurements. I had (a lot) more setbacks than just the main stud nuts and deep socket issues that I mentioned earlier. I lost my brother and have been suffering all that loss of very close family brings. I've also been helping my sister-in-law with a lot of de...

Re: BBC gear drive

so far i've looked at milodon, RCD and Donovan gear drives. They all look good. One thing i think is at least with the milodon it looks like you have to modify your block in a way that there is no going back. Thats not good. I have seen that issue where guys want to go back to std. timing cover but...

Re: 0.006" valve clearance in new DOCH CAMs - Too tight?

I see European makers offer new billet cams for my DOCH application (Fiat original twin cam). They suggest valve clearances as low as 0.006" and typically no more than 0.008". This seems awful close to me. Factory clearance was 0.016/0.020". What would be the acceptable clearance range? One cam mak...

Re: Piston pin "end play" ? How much is ok ??

Hey guys, One of my customers has a set of brand new forged pistons that he brought by for me to look at. The pistons use round wire lock type pin retainers. On this set of pistons the pins can move back and forth almost 1/8" Every set of decent pistons I have seen have very little if any movement ...

Re: Small cams on 106-108 LSA’s

I believe the rest of the combo needs to be taken into account when discussing LSA. Tight LSA cams generally work with FREELY flowing exhaust systems. A restrictive exhaust KILLS a cam with overlap. Small cams are often used with stock exhaust manifolds and small exhaust systems. Overlap is bad wit...

Re: BBC crankshaft with no name???

the crank is junk to me as i mic'd it and sure enough the rod journals are all tapered towards the cheek by almost a .001. Its worthless and not worth grinding to me. If you paid new cost for it that sucks but the cost of a grind to repair an otherwise good crank is worth it regardless if its steel...
